DETAILED DESCRIPTION OF EMBODIMENTS

An exemplary embodiment of an apparatus for launching a flying disc is illustrated schematically in FIGS. 1A-1B, 2A-2B, 3A-3B, 4A-4B, and 5A-5B. In each pair of Figures, the “A” figure shows the disc launcher alone, while the “B” figure shows the disc launcher with a disc 900 in position to be gripped by the disc launcher (but not necessarily gripped). The disc launcher comprises an elongated handle member 12, an elongated launching member 14, a disc gripper 16, and a release mechanism 18. The launching member 14 is connected at its proximal end to the distal end of the handle member 12 so as to permit relative angular motion of the launching member and the handle member. Any suitable mechanical linkage can be employed for connecting the handle member 12 and launching member 14 that enable the relative angular motion, including but not limited to a clevis-and-pin joint (as in the exemplary embodiment), a hinge joint, a ball-and-socket joint, a disc-and-slot joint, or a universal joint. The clevis-and-pin joint of the exemplary embodiment comprises a disc-shaped rearward projection 14 a of the launching member 14 positioned between a pair of opposed, spaced-apart disc-shaped forward projections 12 a of the handle member 12 (FIGS. 7A-7C and 8A-8D). The handle member 12 and the launching member 14 can be connected to permit angular motion about multiple axes; typically, the handle member 12 and the launching member 14 are connected to permit angular motion about a single rotation axis, which would be oriented roughly perpendicularly relative to a plane of motion in which the disc launcher would be swung when used to launch a disc (as in the illustrated exemplary embodiment). The handle member 12 and launching member 14 can comprise metal, plastic, wood, composite, or any other material or material combination having suitable strength and stiffness. Alternatively, the handle member 12 and the launching member 14 can comprise a single elongated flexible resilient member, and bending of the resilient member can provide the relative angular motion (as in FIGS. 14A-14C). Such a flexible resilient member can comprise any material having a suitable combination of strength and flexibility.

The disc gripper 16 is connected to the distal end of the launching member 14 and can be arranged in any suitable way for gripping the flying disc 900. As illustrated schematically in FIGS. 6A-6C, the release mechanism 18 is operatively coupled to the disc gripper 16 and arranged so as to (i) enable the disc gripper 16 to hold the flying disc 900 with the handle member 12 and the launching member 14 forming an angle (A) less than a release angle (R) and (ii) cause the disc gripper 16 to release automatically the held flying disc 900 as the handle member 12 and the launching member 14 move to the release angle (R) from the angle (A) less than the release angle (R). The handle member 12, the launching member 14, and the disc gripper 16 are typically arranged to enable motion only about a single rotations axis and so that the rotation axis is substantially perpendicular to the held flying disc 900. Other suitable orientations of the held disc 900 relative to the rotation axis can be employed. The automatic release of the disc upon the handle and launching members reaching the release angle ensures that the disc leaves the launcher at a consistent point in its trajectory when swung by a user, enhancing the ability of the user to accurately direct the launched disc in a desired direction.

In the exemplary embodiment, the disc gripper 16 comprises a pair of opposed gripping

members

112 and 114 arranged for gripping the flying disc 900 positioned between them (FIGS. 7A-7C and 8A-8B). At least one of the opposed gripping members (gripping member 114 in the exemplary embodiment) is pivotably connected to the launching member 14 so as to enable relative movement of the gripping

members

112 and 114 away from and toward one another. As shown in the exemplary embodiment, the opposed gripping

members

112 and 114 are arranged to hold the flying disc by engaging the disc's top and bottom surfaces, however, any suitable arrangement of the disc gripper 16 or gripping

members

112 and 114 can be employed. The gripping

members

112 and 114 can comprise metal, plastic, wood, composite, or any other material or material combination having suitable strength and stiffness. One or both gripping members can further include friction material or resilient material 124 positioned in any suitable way to make contact with the held disc 900 (indicated in FIGS. 7B and 7C). Suitable resilient materials can include but are not limited to natural or synthetic rubber, neoprene, vinyl, various plastics; any suitable friction material can be employed (e.g., sand-paper-like materials). One or both of the gripping

members

112 and 114 can be curved to engage a portion of the disc's outer circumference in any suitable fashion. As shown in the exemplary embodiment, the gripping member 112 is curved so as to enable engagement with the inner circumferential surface of the lip on the underside of the flying disc 900 held between the opposed gripping

members

112 and 114.

In the exemplary embodiment, the release mechanism 18 is operatively coupled to at least one of the opposed gripping

members

112 or 114 so as to (i) bias the opposed gripping

members

112 and 114 toward one another to hold the flying disc 900 between them with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R) and (ii) release automatically the bias on the gripping

members

112 and 114 thereby releasing the held flying disc 900 as the handle member 12 and the launching member 14 move to the release angle (R) from the angle (A) less than the release angle. The release mechanism 18 can be thus coupled in any suitable way. In the exemplary embodiment, the pivotably connected gripping member 114 comprises an elongated distal arm of a lever and is arranged for gripping the flying disc 900. The lever also comprises a proximal lever arm 116 arranged for engaging the release mechanism 18, and is pivotably connected to the launching member 14 at a pivot point 118 between the

lever arms

114 and 116.

The proximal lever arm 116 of the exemplary embodiment includes a linear ratchet 120 arranged so as to (i) engage the release mechanism 18 to bias the gripping

members

112 and 114 toward one another with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R) and (ii) disengage automatically from the release mechanism 18 and release the bias on the gripping

members

112 and 114 as the handle member 12 and the launching member 14 move to the release angle (R) from the angle (A) less than the release angle. In the exemplary embodiment, release mechanism 18 includes a flange 14 c on the launching member 14 that is arranged so as to (i) engage the linear ratchet 120 with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R) and (ii) disengage automatically from the linear ratchet 120 as the handle member 12 and the launching member 14 move to the release angle (R) from an angle (A) less than the release angle. In an alternative embodiment, such a flange could be positioned on handle member 12 instead (described further below). The proximal lever arm 116 can be arranged to engage or disengage from the release mechanism 18 in any other suitable manner.

In the exemplary embodiment, one of the projections 12 a can be arranged to include a cam portion 12 c (FIGS. 8A-8D and 9A-9B). The cam portion 12 c is positioned to allow engagement of the linear ratchet 120 and the flange 14 c with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R), thereby retaining the disc 900 held between

gripping members

112 and 114. Upon the launching and handle

members

12 and 14 reaching the release angle (R), the cam portion 12 c forces disengagement of the linear ratchet 120 from the flange 14 c to allow movement of the

lever arms

114 and 116, thereby releasing the disc 900. The linear ratchet 120, lever arm 116, or lever arm 114 typically should be sufficiently resilient to maintain engagement of the linear ratchet 120 and the flange 14 c when gripping the disc 900, while enabling the cam portion 12 c to force disengagement of the linear ratchet 120 from the flange 14 c. The release angle (R) is determined by the location of the cam portion 12 c on projection 12 a. The release angle (R) can be a fixed parameter of the disc launcher, or can be made adjustable, e.g., by arranging the cam portion 12 c to be fixed at various angular positions on projection 12 a (FIGS. 9A-9B). Any suitable arrangement for enabling adjustment of the release angle can be employed.

In an alternative embodiment (FIGS. 13A-13D), the flange 14 c can be positioned on projection 12 a of the launching member 12 and arranged so that the flange engages the linear ratchet 120 with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R), as in FIGS. 13A and 13C, but disengages from the linear ratchet 120 upon reaching the release angle (R), as in FIGS. 13B and 13D. For example, the cam portion 12 c can act as a portion of the flange 14 c. The radius of the flange 14 c can be made to vary substantially continuously over a cam portion 12 c, so that the edge of the flange 14 c engages the linear ratchet 120 at the angle (A), but does not engage the linear ratchet 120 at the release angle (R). Alternatively, the radius of the flange 14 c can vary discontinuously (not shown). For example, the flange 14 c can have a substantially constant radius that enables engagement of the linear ratchet 120, but can also be provided with a radial slot or notch that aligns with the linear ratchet 120 at the release angle (R) to allow disengagement of the linear ratchet from the flange 14 c. Any other suitable arrangement of the release mechanism for engaging or disengaging from the linear ratchet can be employed.

The angle (A) formed between the handle member 12 and the launching member 14 typically has some minimum angle imposed by the nature of the mechanical joint connecting them. It may be possible to arrange the handle member 12 and launching member 14 so that the minimum angle is anywhere from 0° to 180°, but the minimum angle is typically greater than about 60°, more typically greater than about 90°, and most typically greater than or equal to about 120°. The angle (A) referred to in the present disclosure will typically be greater than the minimum angle and only extend beyond the release angle (R) by a few degrees (perhaps as much as about 10°). The release angle (R) is typically less than or equal to about 180°, and can range between about 150° and about 180° (note that angles greater than 180° indicate that the handle and launching members have moved through and beyond a parallel arrangement). The handle member 12 and the launching member 14 can be arranged so as to limit the relative angular motion to less than a maximum angle, which is at least as large as the release angle (R). In some instances the maximum angle is about equal to the release angle (R); in other instances the maximum angle is greater than the release angle (R).

In the exemplary embodiment, the handle member 12 and the launching member 14 are arranged so as to limit their relative rotation between the minimum and maximum angles. A wedge-shaped depression 14 b on the rearward projection 14 a of launching member 14 receives a wedge-shaped protrusion 12 b on one of the opposed surfaces of forward projections 12 a of handle member 12 (FIGS. 7A-7C and 8A-8D). The angular positions and subtended angles of protrusion 12 b and depression 14 b determine the maximum and minimum angles for relative motion of the launching and handle

members

14 and 12. Any other suitable mechanical arrangement can be employed for limiting the angular motion.

A method for launching the flying disc comprises: (i) arranging the handle member 12 and the launching member 14 to form an angle (A) less than the release angle (R); (ii) loading the flying disc 900 into the disc gripper 16; (iii) engaging the release mechanism 18 to engage the disc gripper 16 to hold the flying disc 900; and (iv) grasping the proximal end of the handle member 12 (with one hand or with both hands, as desired) and swinging the launching apparatus to cause the handle member 12 and the launching member 14 to move to the release angle (R) and to cause automatically the disc gripper 16 to release the flying disc 900, thereby launching the flying disc 900. Typically, the plane of the swing, the plane of the disc, and the plane in which handle member 12 and launching member 14 rotate relative to one another are approximately parallel to one another to result in proper flight of the flying disc. Other arrangements can be employed if suitable or desired. A typical swing is illustrated schematically in FIG. 12.

Use of the disc launcher will typically include a backswing after the disc is loaded into the disc gripper. During the backswing, inertia will tend to move the launching member toward or beyond the release angle, causing the disc to be released prematurely. An variety of mechanisms or arrangement can be employed to prevent (or reduce the likelihood of) such a premature release. In the exemplary embodiment illustrated schematically in FIG. 10, a spring-loaded detent mechanism (depression 14 d in the edge of projection 14 a of launching member 14 and a rounded, spring-loaded piston 12 d reciprocally moveable within handle member 12) can be employed to retain the launching member at a fixed loading position only a few degrees less than the release angle. Tension or friction on the detent mechanism can be made sufficiently large to retard motion of the launching member so as to substantially prevent movement of the launching member toward the release angle during a typical backswing, but sufficiently small so as to allow movement away from the release angle during the early portion of the forward swing and then toward and to the release angle during the latter portion of the forward swing (to release the disc). Alternatively, a manually operated bolt or pin could be employed to prevent angular motion of the launching member during the backswing and allow such motion during the forward swing, or any other suitable manual or automatic mechanism can be employed.

The direction of disc flight relative to the swing, the distance traveled by the launched disc, and the character of the disc's flight each depend on the dimensions and arrangement of the disc launcher. Any desired lengths can be chosen for the handle and launching members. The handle member is typically less than about 3 feet long, and often between about 2 feet long and about 3 feet long; the launching member is typically less than about 2 feet long, and often between about 1 foot long and about 2 feet long. A longer handle member 12 can result in longer disc flight, but too long of a handle member impedes swinging of the launcher due to increased weight and air resistance. The relative lengths of the launching member 14 and handle member 12 affect the amount of spin imparted onto the launched disc, which can be optimized empirically for each type of disc, for each user, or for desired disc flight characteristics. Both handle member 12 and launching member 14 can be constructed with telescoping or interchangeable shafts or barrels, to enable adjustments of their lengths to achieve such optimization (FIG. 11). Likewise, the precise shape, size, or arrangement of the disc gripper 16 will affect the distance achieved of disc flight characteristics. Different disc grippers 16 can be provided and interchanged on the end of launching member 14, to accommodate different users or different discs (FIG. 11), including discs approved by the Professional Disc Golf Association (PDGA). As already described above, the release angle or the maximum or minimum angles can be adjusted to the swing characteristics for a specific user. Most of the preceding adjustments are typically made empirically, based on observed flight or performance characteristics of launched discs.
